This study examines the separation performance achieved using the Reflux Flotation Cell (RFC) when treating low economic value coal waste streams over a range of feed solids concentrations. Feed solids concentrations of 1.3, 2.4 and 5.7 wt% were examined using a fine coal suspension of nominally 50 wt% head ash, covering the …

Additionally, the use of high frother concentration can result in persistent and too stable froth formation, leading to overflow in the flotation cells, pumping problems and handling difficulties in the flotation concentrator (Bournival et al., 2017a, Wei et al., 2014). As a consequence of this significant influence of frothers on the overall ...

The objective of this paper was to quantify the performance of a novel flotation cell, the REFLUX™ Flotation Cell, using low-grade ores sourced directly from the industry for the first time. Two low-grade chalcopyrite ores were studied, both containing about 1 wt% copper, and one being slower floating due to the surface-active slime …

Both studies suggested that the ratio between high and low turbulent zones within a flotation cell affects performance. Hall and Dell (1989) showed that in a cell with a larger turbulent zone, i.e. a shorter cell, and at a certain optimum air rate, higher flotation rates were obtained.

Flotation Cells (Froth Flotation) were developed to separate and recover high value Sulphide ores from low grade ore bodies. The ore is crushed and milled at the concentrator in a process known as comminution, where the mineral is in suspension in slurry. The particle size for mineral being recovered is generally less than <0.1mm.
